Accpac 5.6 on MSSQL. Four invoices printed in August and sent to customer - lines do not match the total. Invoices reprinted today printed with correct line info. Customer has two companies. After exhausting any and all logical possibilities (incorrect form code, etc) I explored some illogical ones, and found that the line items printed in the original printing were from the batch and item numbers in the OTHER COMPANY! Anyone ever seen this?

The only time I've seen this is when the invoice form was incorrectly written. I've never seen it happen straight in a database using an out of the box invoice form.
